Front

What is a rigid transformation?

Back

A transformation that preserves distance and angle measures.

Front

What is a dilation in geometry?

Back

A transformation that alters the size of a figure but not its shape.

Front

What is the scale factor in a dilation?

Back

The ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Front

What is the definition of a translation in geometry?

Back

A transformation that moves every point of a figure the same distance in the same direction.

Front

What is the formula for the area of a square?

Back

Area = side^2.
